Résumé
Objective To investigate the risk difference of early neurological deterioration (END) in minor stroke patients with large artery atherosclerosis (LAA) and small vessel occlusion (SVO). Methods From January 2012 to August 2016, consecutive patients with first-ever acute ischemic stroke registered in the Nanjing Stroke Registration System were enrolled. The patients with minor stroke whose National Institutes of Health Stroke Scale (NIHSS) ≤3 on admission were screened. Propensity score matching analysis and McNemar's test were used to analyze the risk difference of END in minor stroke patients with LAA and SVO. Results A total of 778 patients with minor stroke were included, including 249 with LAA, 183 with SAO, and 145 matched pairs with propensity score matching method. The proportion of patients with END in the LAA group was significantly higher than that in the SVO group (6.2% vs. 1.4%; P<0.001). Conclusion Minor stroke due to LAA is more prone to have END than that due to SVO.

Objective To investigate the relationship between the times of thrombectomy and the prognosis of acute ischemic stroke. Methods From June 2014 to June 2016,the clinical data of 61 consecutive patients with ischemic stroke treated with emergency endovascular thrombectomy in Jinling Hospital,Medical School of Nanjing University were collected retrospectively. According to the times of thrombectomy,they were divided into either a routine thrombectomy group ( <3, n =48 ) or a multiple thrombectomy group (≥3,n=13). The modified Rankin scale (mRS) was used to evaluate the neurological function prognosis at 90 d in both groups of patients. The mRS score 0-2 was defined as good prognosis,3-6 were defined as poor prognosis,and 6 was death. Univariate analysis was used to compare the differences between the groups (excluding the patients whose DSA data missing or of poor quality). Spearman correlation analysis was used to evaluate the relationship between the times of thrombectomy and prognosis and fatality rate. Results Univariate analysis showed that the recanalization rate of the patients in the routine thrombectomy group (73. 9%[34/46] vs. 25. 0%[3/12],P =0. 005) and the rate of good collateral compensatory (55. 6%[25/45] vs. 8. 3%[1/12],P =0. 004) were higher than those in the multiple thrombectomy group. The incidence of symptomatic intracranial hemorrhage in the routine thrombectomy group was lower than that in the multiple thrombectomy group (14. 6%[7/48] vs. 53. 8%[7/13],P =0. 003). The mortality rate at 90 days was 18. 0%(n=11). Further Spearman correlation analysis showed that the times of thrombectomy were moderately positive correlated with the mortality rate ( r=0. 517,P=0. 000). There was no significant correlation between the times of thrombectomy and the good function prognosis (r=0. 076,P=0. 560). However,the effects of the differences between recanalization rate,collateral compensation and symptomatic intracranial hemorrhage could not be ruled out. Conclusion Emergency intravascular interventional therapy of multiple thrombectomy is positively related to the mortality rate at 90 d in patients with acute ischemic stroke,however,a study with larger sample is needed to confirm it.

Résumé
Epidemiological studies indicated that dietary tiber was inversely associated with stroke risk.Epidemiological studies have confirmed that increased dietary fiber intake can reduce the risk of stroke.Animal experiments and clinical studies have shown that dietary fiber intake may reduce the incidence of stroke by reducing vascular risk factors,such as hypertension,diabetes,dyslipidemia,and obesity.The direct mechanism of increased dietary fiber intake reducing stroke risk remains to be further studied.Clinicians should pay attention to the important role of dietary fiber,guide the patients with stroke and individuals at risk of stroke to increase consumption of fiber-rich fruits and vegetables.
